SERAPHIN PREVOST, OF NEW YORK, N. Y., ASSIGN OR OF ONE-HALF OF HIS RIGHT TO ROBERT PIERCE, OF NE\V YORK.

COMBINED SETTING-RULE AND BODKIN.

SPECIFICATION forming part of Letters Patent No. 233,545, dated October 19, 1880.

Application filed September 4, 1880.

To all whom at may concern Be it known that I, SERAPHIN PREVOST, of New York, in the county of New York and State of New York, have invented certain 5 new and useful Improvements in Combination Setting-Rules and Bodkins; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to whichit'ap- 1o pertains to make and use the same, reference beinghad to the accompan yin g drawings, which form apart of this specification.

Figure l is a view, in perspective, of the rule closed. Fig. 2 is a similar view of the rule ex- 1 tended showing the sections and the bodkin. Fig. 3 is a view of the sections detached. Fig. 4 is a cross-section of the rule. Fig. 5is a perspective view of the slide detached; and Fig. 6 is a similar view of the sheath or shell.

The object of this invention is to provide a combination or extension setting-rule and bodkin for compositors use in the printing business, wherebyit will be only necessary for the compositor to provide himself with the single 25 improved rule to enable him to properly set all measures of type where he is now compelled to possess a different rule for each measure to accomplish this result; and to this end the invention relates to the improved features of construction and combination hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, similar letters of reference indicate corresponding parts 3 in the several figures.

A indicates the sheath or shell of the setting-rule, the lower edge of which is beveled after the manner of printers brass rule, and the ear B is pivoted and provided with abod- 4o kin, C, which, when closed, shuts the end of the sheath, and when open is used to remove a type when necessary.

1) designates a slide or extension which exactly fits within the shell A, and is provided 5 with a band or head, E, of precisely the same thickness and shape as the shell A, so that when the slide is pushed in to its limit the head E abuts against the end of the sheath A,

and the whole presents the appearance of an ordinary setting-rule for printers use.

The sections G, H, I, K, L, and M are of the same configuration in cross-section as the sheath, and are, respectively, one, two, three, four, five, and six ems pica in width, and are about the size of agate type in thickness, as is also the shell A. These sections are to be slipped upon the slide D when it is desired to increase the length of the rule by extending the slide, and such section or sections should be used as will extend the rule and fill up the slide to the length of the measure required to be set.

The standard sizes of the rule are twelve ems and twenty-three ems pica, but will be manufactured in any size and with any numberof sections desired, of German silver or brass, nickel-plated or naked, to suitthe trade.

By this rule, instead of using a different rule for each different measure to be set, the compositor is enabled to adjust the rule by means of the sections to any measure he may desire up to double the measure of the closed rule. This is not only a saving of time and inconvenience, but is also a saving of a multiplicity of rules. It is a saving to the employer, who is compelled to out up large quantities of brass rule each year to furnish the printers with setting-rules. It is a saving to the piece-hands, who lose much valuable time in hunting up or making setting-rules when called upon to set a variety of difi'erent measures. It gives to the compositor a rule by which he can set his stick to any number of picas without the use of leads, the sections being cut to the exact standard measure.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The herein-described combination or extension rule, composed of the shell A, in combination with the slide D, provided with the head or band E, and adapted to receive the sections G H I, 860., substantially as and for the purposes set forth.

2. The combination setting-rule for printers, consisting of the shell A, slide D, having band E, and the sections G H I, 850., constructed, In testimony that I claim the foregoing as combined, and operating substantially as and my own I have hereto aflixed my signature in 10 for the purposes set forth. presence of two witnesses.
